Hypsibius pallidus Thulin 1911 

Hypsibius pallidus  shows quadrangular or granular-shaped macroplacoids, as a difference from Hypsibius convergens  and H. dujardini  , which have rod-shaped macroplacoids. In addition, this species has doubleclaws similar to those present in Ramazzottius oberhaeuseri  . Mean body size, among the 14 individuals collected, was 534 μm (SD 147), range 308 to 803 μm. The species is considered cosmopolitan ( McInnes 1994). In the Iberian Peninsula, it has been recorded for Spain ( Rodríguez Roda 1946, 1952; Maucci & Durante Pasa 1984; Lewin Osorio 1984) and Portugal ( Da Cunha 1941, 1944a, 1947 b; Fontoura 1981). This is the first time it is recorded for Madrid Province ( Table 2). Hypsibius pallidus  was found at 7 sampling points (Table 3) from LF and MR samples.
